And some insist energy efficiency is unimportant.


I assume you’re roughly estimating 12 hours at 0.50 GPH, for total of 6 gallons of gasoline. At $5/gallon, yeah, that’s $30. I think that may be a little on high side because the generator won’t be at 50% (2,000 Watts) all night, but your general point is valid.

With portable inverter generator, small space, small A/C, etc. we use one tank of 1.3 gallons overnight (closer to 10 hours). Maybe $7 worth of gas at today’s rate, though we haven’t boondocked since Fall when gas was cheaper. I wouldn’t use a portable generator at WM or Cracker Barrel anyway.

Generators are indeed not very efficient, though new Onan 2800i with a Power Saver A/C should cool at around 0.20 GPH at night based on specs. If so, it would make a big difference in total fuel cost. Not an option for you though.
